Abstract

L'invention concerne un appareil pour suivi de pointeur lumineux comprenant un module de source lumineuse pour projeter un faisceau lumineux sur une surface, un module de capture d'image et un module émetteur. Le module de capture d'image détecte une position sur la surface d'un point lumineux visible généré par le faisceau lumineux projeté qui frappe la surface. Le module émetteur transmet la position du point lumineux visible à un dispositif distant pour télécommander un dispositif.
